Iégor Reznikoff is thus a specialist in ancient and medieval resonance but also in resonance in caves decorated with the Paleolithic and, moreover, in modern buildings: by this work, he owes him the notion of architectural sound heritage. Hearing it in a great Romanesque or Gothic resonance is an unforgettable musical experience. Invited to numerous international festivals of early music and music of oral traditions, Iégor Reznikoff has given concerts in most European countries as well as in the United States and Japan. Professor at the University of Paris, he has taught and still teaches in several prestigious conservatories but also in many religious communities. He had the honor of singing for the Dalai Lama (Zurich 1991), in Shinto ceremonies for the millennium celebrations (Kyoto 2000), as well as in exceptional sites such as the Temple of Apollo at Delphi or the Saint Basil François in Assisi.

A specialist in ancient art and music, Iégor Reznikoff gave his first concerts in the field of ancient Christian song in 1975. Today world famous, his then fundamentally new interpretation of these songs, as well as his theoretical and historical works , have since greatly influenced the evolution of the understanding and interpretation of ancient song and in particular Gregorian chant. We owe him above all the revival of the great solo song that he developed in all its splendor. His approach to ancient song is rigorously based on ancient manuscripts and neumatic notation, on the comparative listening of the great related spiritual oral traditions and above all - and this work remains unique until now - on the right intonation antique ranges, in particular in the natural resonance of the buildings, giving back to the architecture of ancient churches its essential contemplative dimension.
